This invention relates to a power cycle and has particularly to do witha combination starter brake assembly for use in such cycles.

The cycle under consideration is of the type intended to seat aplurality of passengers in fore and aft positions, and it is the purposeof the present invention to provide a braking system which may beactuated at a plurality of points along the cycle and also to provide acombination starter lever which serves also as a brake".

Drawings accompany the spectification, and the various views thereof maybe briefly described as:

Figure 1, an assembly view showing a portion of the power cycle togetherwith the brake operating system.

Figure 2. a view showing the combination starter and brake lever instarting position.

Figure 3, a view showing the brake lever in braking position.

Figure .4, a view showing the combination starter brake lever in idlingposition.

Figure 5, a view showing a completed assembly of a power cycle withseating arrangements for a plurality of passengers.

Referring to the drawings, the frame of the power cycle is shown havinga longitudinally extending member It]. A rear wheel l2 has an actuatingear I4, a brake drum l6, and a brake actuating arm l8. A link isresiliently pivoted to the arm 18 and extends forward to an end 22 of abell-crank lever 24.

A spring 26 on link 20 bears against the stop 28 and against the arm I8so that link 20 may be backed off with respect to the arm. However,

a stop 30 will actuate the arm l8 when link 20 is placed in tension. Theother end 32 of the 4 Claims. (Cl. 180-33) bell-crank lever 24 is anactuating end having a projecting stud 34 which may serve to receivefoot pressure. Actuation of the brake arm 18 is accomplished by merelyapplying foot pressure downward on the stud 34, the bell-crank 24 beingpivoted at 36 on frame member 10.

An engine 40 is mounted on the frame of the power cycle and suitablyconnected in a manner not shown to a transmission 42 which drives a gear44 connected by a chain 46 to the drive sprocket I4. A starter mechanismhoused in a circular shell 50 serves to start the motor 4|], and apinion 52 is the actuating means for the starter mechanism, details ofwhich are not shown but are commonly known in practice.

The pinion 52 is to be actuated by a gear rack 54 which is formed on abell-crank type of lever 56 which has a wedged shaped end 58 providedwith an arcuate opening 60, one side of which is formed as the gearrack. The pinion lies within this opening 60, and it will be noticedthat the gear rack 54 extends on1y through a portion of the opening sothat in the position shown in Figures 1, 3 and 4 the pinion is free toidle within this opening.

A lever or pedal end of the bell-crank 56 'extends forwardly at 62 andhas a foot plate 64 which extends to the side of the lever and'per-'mits it to be raised to a starting position as shown in Figure 2. Whenso raised, the pinion,

which has a free wheeling motion in acounterclockwise direction, willengage the rack 54 and upon a sudden downward thrust of lever end 62 rod12.

With the above described construction, the arm 62 of the forwardbell-crank may also actuate the brake through the arm 22 and the linkrod 20. When the starter mechanism is being operated, the arm 10 willslip back on the rod 12 and it will be out of action. There is alostmotion connection here which operates only when the block 14 reachesthe stop 16. With the parts in the position shown in Figure 4, a furtherdepression of lever 64 will actuate brake rod 12 as shown in Figure 3.To re-start the engine, it is necessary to retract lever 62 to theposition shown in Figure 2 before pressing down to actuate pinion 52.

It will thus be seen that the brake arm I8 may be actuated by anoperator either sitting to the rear using lever 32 or an operatorsitting forward of the machine using lever 62. Also, when the machine isoperating, the pinion 52 is free to rotate, thus preventing unusual wearon the clutch relation between the pinion and the starter mechanism.

In Figure 5, an assembly of a vehicle in which thestarting and brakemechanism would be used is shown. Surrounding and to the rear of thefront yoke of the vehicle is a shield plate 96, and on the sides of thevehicle are foot rests H0 positioned on a horizontal plane andterminating inwardly at vertical side plates H2. The rear housing of theunit is formed by plates H6 together with a rear housin member I20 and atop closure member I22. A front dirigible wheel I30 and a rear powerwheel I2 support sengers in fore and aft positions, an aengine in saidframe, a brake mechanism on one of said wheels, a brake actuating arm, afirst medal on said vehicle connected to said arm to actuate the same inresponse to foot pressure, 9a (second pedal on said vehicle connected tosaid arm by in llost motion device, a ,starter mechanism ractuated by apinion gear, and a :rack .connected itc :said second pedal to engage:andractuate said {pinion in ,a portion of the stroke of said ,pedal,the .of the .stroke serving to actuate ,sai'd lbrake arm.
